I have had it for 18 months. the period between recharges has become shorter and now it fails to recharge. Can I change the battery?

Same problem here, had mine for about the same time and now the battery just won't hold a charge and the water pressure isn't enough to floss properly.I managed to find a pdf of the manual on the Panasonic site (Google for EW1211), and once you figure it out it's quite easy to remove the insides to get at the batteries. Just follow the "disposal" instructions. I can only find 1 place that sells the batteries (http://www.buyspares.co.uk/product.pl?pid=2985391) and they cost just under £15 including shipping. I am going to take a risk and purchase a pair and hope that I can fit them back ok and make it work. It's that or a costly purchase of a replacement. Hope this helps.

Can this oroduct be used with normal plug or just with the shaver one?

My EW-1511 (purchased here) came with a 2-prong "shaver plug". Adapters (available separately) are available to use a standard 13A UK plug.

How long does it take to charge EW1211W?

Charging is completed in about 15 hours.
